APPARATUS AND METHOD FOR BALANCING OF BATTERY CELL'S CHARGING CAPACITY

摘要

Disclosed is an apparatus for balancing the charging capacity of a battery cell. The apparatus for balancing the charging capacity of a battery cell according to the present invention includes a voltage sensing part that measures the charging voltage of each battery cell and the discharging voltage and outputs a voltage measurement signal, and a control part that calculates the time average value of the discharging voltage and the charging voltage for each battery outputted from the voltage sensing part and compares the calculated charging state voltage of each battery to select a battery cell required for balancing, and output a control signal to a balance circuit corresponding to the selected battery cell. According to the present invention, the changing balancing of a battery pack is performed in successive charging and discharging processes. [Reference numerals] (120) Control unit;(150) Memory unit
